lvitmwo UNITED STATES PATENT OFFICEQ SACK-SCALE.

Application filed January JG, 1880.

To (tZZ 2071 0112 it may concern.-

Be it known that I, GEORGE P. Monnocic, a citizen of the United States, residing at Plymouth, in the county of Marshall and State of Indiana, have invented certain new and useful Improvements in Grain-Meters; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thcreon,which form a part of this specification.

This invention relates to grain-meters; and it consists in details of construction and novel combinations of parts, more particularly here inafter referred to, and pointed out in the claims.

In the annexed drawings, Figurel is a front view of a machine constructed in accordance with and adapted to carry out my invention. 2 is a plan view with parts broken away. Fig. is a section on the line XX. of Fig. 2 of the upper portions. Fig. 4 is a section of a similar part on the lineY Y of thesame figure.

The frame is closed in on three sides by the sides A and back A, and is divided centrally by avertical partition, A forming two compartments, l3 l3. Levers G, pivoted on the inner sides of the compartments at c, are arranged in pairs, one for each compartment, as shown. The rear ends ofeach pair ofthe levers are united by a yoke, 0, having arearwardlyprojecting arm, 0. Frames or stirrup-platforms I) depend from the inner ends of the pairs of levers, and are of such a length that when the one rests on the bottomof the frame the other is at a distance above such bottom. These platforms are intended to support grainrecepiacles, which ordinarily are bags. To keep the open ends distended and support the bags while receiving the grain,wire frames 15 are attached to the upper ends of the sides (1 of the platforms, over which the end of the bags may be stretched and retained by hooks c.

A grain-spout, F, of ordinary construction, designed to be connected with a thrashingmachine, has two branches, F, each of which terminates at a point directly above the plat forms D. A cut-off, j, pivoted within the spout a t the point of divergence of the branches Serial No. 189,823. (No model.)

F, controls the discharge of grain through either branch, for the purpose presently described.

A register, G, of usual construction, is mounted on the upper portion of the frame, and a sliding pawl, g,working through a guide, 9, actuates the registering mechanism. A verticallypivoted lever, II, is connected at one end to the pawl g, and an arm, 72/, projects from its other or lower end through a slot in the side of the registers ease. The upper edge of the partition A has a notch or recess, a, formed tl1erein,within which a rock-shaft, 'i, is journaled. Keyed to this shaft is a ment, I, and arm J. The latter projects vertically upward, and is slotted atj near its upper end, to receive the ends of the arm h and leverf, which project therethrough in opposite directions. The lever f extends rearrwardly from the pivotal centerof the cut-off).

From the sides (Z of the platform adjacent the partition A are extended upward cords 7;, which connect with the opposite ends of the segment I.

In practice, it being desired to weigh off or measure a certain quantity of grain into separatc parcels as it is delivered through the spout F, a counterpoise, K, of the requisite weight is adj usted on the arm of the yoke to a point representing the quantity of grain to be weighed. The bag orreceptacle being in position under one of the spouts and the cut off turned to one side or the other to shut oil" the branch F not in use, as represented by dotted lines, Fig. 2, the grain will discharge into the receptacle till it ovcrlralanees the weight K, when the platform will descend, causing a corresponding elevation of the other, by reason of the segment I and cords 7.. Si multaneously with this movement of the platforms the arm .l is vibrated, shifting the position of the cut-off, opening the branch F previously closed, and shutting off that before opened, and at the same time giving an impulse to the pawl g, by which a register is made. \Vhilc the grain is flowing through the branch now opened the iilled receptacle is removed and an emptyone put in its place. Thus no time is lost in weighing and packing, and a continued iiow of grain is preserved through the spout.

The meter is automatic in its operation, and after being once set to weigh off a certain quantity of grain needs no further attention on the partof the attendant, save the remov- 5 ing of the filled receptacles and replacing the same by empty ones.

Having thus described myinvention,what I claim, and desire to secure by Letters Patent, 1S

1. The combination of the vertically-movable platforlnsfii segment pivotall y supported above themfconnections uniting the platforms with the opposite ends of the segment, an arm projecting from the axial line of the segment,

a bifurcated grain-spout, a pivoted cut-off lo- 7 cated at the point of divergence of the spout,

and a lever projected from said cut-0E and engaged by said -arm, whereby the vertical movements of the platforms will effect a si- 20 multaneous adjustment of the cut-off.

2. The combination, with the verticallymovablc platforms, a pivoted segment, connections uniting the platforms with the opposite ends of the segment, a pivoted cut-off hav- 2 ing a lever extending therefrom, and an arm projecting from the axial line of the segment and interlocking with saidlever, of a register, a sliding pawl engaging its mechanism, a vertically-pivoted lever connected at its upper '30 end to the pawl, and an arm projecting laterally from its lower end and engaging the arm extending from the axial line of the segment, whereby said arm simultaneously actuates the register and cut-off, substantially as described, and for the purposes specified.

3. A grain-meter comprising the following elements in combination: a frame, a divisionwall dividing the same into two compartments, a pair of levers pivoted to the sides of the compartments, yokes uniting the rear ends of 0 each pair, and having rearwardly-projecting arms to receive counterpoises, platforms suspended from the front ends of each pair of levers, a segment pivoted in line with the division-wall, connections uniting the plat- 45 forms with the segment, a slotted arm projected from the axial line of the segment, a register having an actuating-arm engaging the slot in said arm, and a bifurcated grain-spout provided with a pivoted cut-ofi havinga rear- U ward-projecting lever working in the slot in the said arm, the parts being constructed and operating in the manner substantially as hereinbefore specified.

In testimony whereof I aifix my signature in 55 presence of two witnesses.
